IMPROVEMENT IN- CUTTING AND BORING ATTACHMENTS FOR LATHES.

Specification forming part of Letters Patent No. 201,948, dated April 2,1878 application filed January 5, 1878.

To all whom iii-may concern:

Be it known that I, MATHEW RICE, of Augusta, in the county of Richmondand State of Georgia, have invented a new and Improved Outtin g andBoring Attachment to Lathes, of which the following is a specification:

In the accompanying drawings, Figure 1 represents a side elevation of myimproved cutting and boring attachment to lathes. Fig. 2 is an end view,partly in vertical transverse section; and Fig. 3, a side view of theattachment, arranged in vertical position for boring and other purposes.

Similar letters of reference indicate corresponding parts.

My invention relates to a hand-machine for shaping, molding, &c., andwill first be described -in connection with the drawing, and thenpointed out in the claim.

A represents the supporting-frame, in three bearings of which turns theshaft B, the said frame being in two sections, of which the longer isprovided with the planing-knives,

and the shorter with the balance-wheel D and V-pulley D. The shaft Bextends beyond both sections of frame, and is provided with a socket forthe reception of interchangeable cutting-tools at both ends, for thepurpose of attaching emery-wheels. I The face-plate (shown in Fig. 3 ofthe drawing) receives the sand-paper for polishing wood or iron, andmoves upon a threaded shaft, to which it is held by a jam-nut. The frameis held to the work by means of handles A.

The band E passes over pulley D and between guide-rolls E, over thesuspended pulley E and over the lathe-pulley. The entire attachment isbalanced by aweight, F, attached to a cord, F passing overaceiling-pulley, F to the pulley E, to which it is secured by aswivelhook that turns with the belt in any direction. This enables thedevice to be carried to the work with great facility without cutting orinjuring the belt.

G G are adjustable guides on the shaft B, and having flanges that formslide-bearings and are provided with bolt slots. These guides lap thesupporting-frame on the inside, and are held at the desired adjustmentby the bolt and the nut thereon. They are also provided with thevertical detachable and adjustable gages G G, that slide on the saidguides to regulate the depth of out, while the guides direct and steadythe device to any desired templet or design.

Having thus described all that is necessary to a full understanding ofmy invention, what I claim as new is- The lathe attachment, consistingof the supporting-frame A, having handle A, the shaft B, the pulley D,balance-wheel D, adjustable gages G, and guides G, as shown anddescribed.

MATHEW RICE.
